3D Analysis of the TCR/pMHCII Complex Formation in Monkeys Vaccinated with the First Peptide Inducing Sterilizing Immunity against Human Malaria

T-cell receptor gene rearrangements were studied in Aotus monkeys developing high antibody titers and sterilizing immunity against the Plasmodium falciparum malaria parasite upon vaccination with the modified synthetic peptide 24112, which was identified in the Merozoite Surface Protein 2 (MSP-2) and is known to bind to HLA-DR beta 1*0403 molecules with high capacity. Spectratyping analysis showed a preferential usage of V beta 12 and V beta 6 TCR gene families in 67% of HLA-DR beta 1*0403-like genotyped monkeys. Docking of peptide 24112 into the HLA-DR beta 1*0401-HA peptide-HA1.7TCR complex containing the VDJ rearrangements identified in fully protected monkeys showed a different structural signature compared to nonprotected monkeys. These striking results show the exquisite specificity of the TCR/pMHCII complex formation needed for inducing sterilizing immunity and provide important hints for a logical and rational methodology to develop multiepitopic, minimal subunit-based synthetic vaccines against infectious diseases, among them malaria.

Experiences, sensations and demands of citizen (in)security: recent complex configurations in Argentina

Over the last decades the issue of insecurity due to an increase in crime rates and its possible impact on the stability of Latin American democracies has sparked an ongoing debate. In this context, the present article studies, for the case of Argentina, how experiences and sensations of insecurity may be articulated to demands for greater punitive rigor. The analysis is based on two types of information. Initially, data from international surveys such as Latinoabarometer are considered. Then, these are compared to data from prolonged on-site observations in a poor neighborhood of a mid-sized Argentine city. The combination of these different types of data shows the complexity of the process. Contrary to what is often assumed, experiences and sensations of insecurity do not lineally lead to demands for greater punitive rigor. The way in which social actors elaborate their experiences of insecurity is highly situational and not systematic. We have found that there is not necessarily a consistent process of ‘meaning construction’ that articulates experiences and sensations of insecurity with political demands.

Leadership: A complex concept awaiting a new explanation?

Leaders have the task of developing future strategy while being consciously engaged in executing current strategy and mapping landmarks, pathways and obstacles which they meet asthey endeavor to traverse challenging, rapidly evolving terrain. In an era in which there is a global leadership credibility crisis, business as usual is no longer an option in the pursuit of the longer-term survival of any organization. The leadership approach to complexity outlined here is based on learning to achieve results through experimentation, learning, and reflection. A case study is presented that illustrates the application of this approach. In this paper, the reader is first introduced to a brief overview of some key definitions and debates, shifting leadership boundaries, and emerging accountabilities and opportunities. This is followed by a summary of some of the key topics and issues that face current and future leaders.

La ense??anza religiosa escolar en el pensamiento actual de la Comisi??n Episcopal de Ense??anza

Resumen tomado de la publicaci??n

Declaración de la Comisión Episcopal de Enseñanza y Educación religiosa : no es una respuesta al Libro Blanco. Será publicado un informe sociológico sobre la formación en los Colegios de la Iglesia.

Se exponen las características más destacadas de la Declaración de la Comisión Episcopal de Enseñanza y Educación Religiosa, redactado por encargo de la Conferencia Episcopal Española en 1968. Así como, las reflexiones que ofrece este documento sobre el objetivo fundamental de la educación de la educación en general y la cristiana, la visión global del proceso educativo, los problemas especiales desde el punto de vista pastoral, la necesidad de superar muchos prejuicios y conseguir la igualdad de oportunidades para el trabajo y, el análisis del valor educativo de los medios de comunicación social y responsabilidad de la sociedad en materia de educación. Por último, se incluye la presentación de esta Declaración y algunos comentarios sobre el mismo.

Fronts from complex two-dimensional dispersal kernels: theory and application to Reid's paradox

Bimodal dispersal probability distributions with characteristic distances differing by several orders of magnitude have been derived and favorably compared to observations by Nathan [Nature (London) 418, 409 (2002)]. For such bimodal kernels, we show that two-dimensional molecular dynamics computer simulations are unable to yield accurate front speeds. Analytically, the usual continuous-space random walks (CSRWs) are applied to two dimensions. We also introduce discrete-space random walks and use them to check the CSRW results (because of the inefficiency of the numerical simulations). The physical results reported are shown to predict front speeds high enough to possibly explain Reid's paradox of rapid tree migration. We also show that, for a time-ordered evolution equation, fronts are always slower in two dimensions than in one dimension and that this difference is important both for unimodal and for bimodal kernels
